Title (EN) METHOD FOR PRODUCING FINE PARTICLES, AND FINE PARTICLES
(FR) PROCÉDÉ DE PRODUCTION DE PARTICULES FINES ET PARTICULES FINES
(JA) 微粒子の製造方法及び微粒子
Abstract:
(EN) The present invention addresses the problem of providing: a method for dry-coating surfaces of nucleic substances having particle diameters of 100 μm or less, said nucleic substances being used as primary particles; and fine particles which are produced by this method. The present invention provides a method for producing particles that are covered with a resin or a fat/oil, which comprises a step for mechanically mixing first particles that contain an active component and have particle diameters of 100 μm or less and second particles that contain at least one of a resin and a fat/oil.
(FR) La présente invention concerne un procédé de revêtement à sec de surfaces de substances nucléiques ayant des diamètres de particule inférieurs ou égaux à 100 µm, lesdites substances nucléiques étant utilisées en tant que particules primaires ; et des particules fines qui sont produites par ce procédé. La présente invention concerne un procédé de production de particules qui sont recouvertes d'une résine ou d'une graisse/huile, qui comprend une étape de mélange mécanique de premières particules qui contiennent un composant actif et ont des diamètres de particule inférieurs ou égaux à 100 µm et de secondes particules qui contiennent au moins l'une parmi une résine et une graisse/huile.
(JA) 本発明の課題は、100μm以下の粒子径を有する核物質を一次粒子として使用し、その表面を乾式コーティングする方法、並びに上記方法により製造される微粒子を提供することである。本発明によれば、活性成分を含む粒径100μm以下の第一の粒子と、樹脂又は油脂の少なくとも一種を含む第二の粒子とを機械的に混合する工程を含む、樹脂又は油脂で被覆された粒子の製造方法が提供される。
